Worked Solution & Example Answer:Which diagram shows the direction of the forces from the water on the inside of the tank? Figure 3 shows three containers A, B, and C - Edexcel - GCSE Physics - Question 3 - 2016 - Paper 1
Step 1
Which diagram shows the direction of the forces from the water on the inside of the tank?
Answer
In this question, we need to identify which diagram accurately represents the direction of the forces exerted by the water on the walls of the tank.
Since the water exerts a force due to its weight, the force acts downwards. At the same time, the force on the sides of the tank is directed inward due to the pressure exerted by the water.
Diagrams A and B depict vertical forces, which are not representative of the lateral forces on the tank's walls.
Diagram C correctly shows the inward force on the sides, whereas Diagram D incorrectly suggests a downward force on the walls.
Thus, the right answer is Diagram C.
Step 2
Part (b) - Details on the containers A, B, and C
Answer
In the context of containers A, B, and C:
- Container A: Contains a mixture or different density liquids, affecting buoyancy.
- Container B: Contains water and mineral oil, displaying different levels due to density differences.
- Container C: Contains water alone, thus showing only one level.
When analyzing the properties of these containers, it becomes essential to understand how density and pressure relate to the behavior of liquids in different configurations.
